1 standard ics quad 2-input nand schmitt trigger bu4093b / bu4093bf / bu4093bfv the bu4093b, bu4093bf, and bu4093bfv are 4-circuit, 2-input nand gates whose input pins all have a schmitt trigger function. as the circuit threshold voltages are different when the input waveform rises and when it falls (v ih , v il ), they can be used for line receivers, waveform rectification, multivibrators, and other purposes in addition to the customary usage as a nand gate. they may be used in place of the bu4011b which uses the same pin connection. features 1) low power dissipation. 2) wide range of operating power supply voltages. 3) high input impedance. 4) high fan-out. 5) direct drive of 2 l-ttl inputs and 1 ls-ttl input. block diagram truth table 1 a 1 2 b 1 3 o 1 4 o 2 5 b 2 6 a 2 7 14 13 12 11 10 9 8 v ss v dd a 4 b 4 o 4 o 3 b 3 a 3 input output ab llh lhh hlh hhl
